INCANDESCENT-LAMP LOCK AND SEAL.

Specification of Letters Patent.

Application filed July 9, 1912.

Patented May 20. if) t 1;.

Serial No. 708,461.

To al l whom it may concern Be it known that we, HUGH DAVIES and JAMES Coons, citizens of the United States, and residents of West New York, county of Hudson, and State of New Jersey, have in Vented certain new and useful Improvements in Incandescent-Lamp Locks and Seals, of which the following is a specification.

In hotels lighted by electricit and in large office buildin s similarly lig ted, considerable loss resu ts from the theft of incandescent lamp bulbs and particularly of that class of bulbs fitted with tungsten and like expensive filaments. In hotels it frequently) occurs that the guests remove the lam ulbs from the sockets and connect cha ng dishes and other electric cooking utensils and electrically heated irons to the light circuit. This frequently results in over-loading the circuit and the consequent burning out of the fuses. Where the fuses are not destroyed there is an excessive consumption of current which is a direct loss to the hotel.

It is the main object of this invention to provide a simple means for locking the incandescent bulb to the socket in such manner that it cannot be removed without the removal of the lock and seal.

Another object of the invention is to provide a simple locking and sealing device which may be readily applied to the lamp sockets now in use and which when in position will permit the lamp to be rotated to a certain extent within its socket so that the lamp bulb is'not rigidly bound or locked.

Another object of the invention is to pro vide a. very simple lock and seal which may readily be placed in position on a lamp socket, and to provide means whereby said lock may be removed and the lamp thereby released without destroying the locking device so that it may be used again.

There are other objects and advantages of the invention which will appear her-*inafter.

In the drawing Figure 1 is an elevation of an incandescent lamp bulb and socket with the locking and sealing device in posi tion; Fig. 2 a similar view showing the locking and sealing'device in sectional view; fa ten the lililtill 'f bani in prnsvd with if de ired.

.be of any desired construction.

The lamp is prmidml with the usual threaded metal plug 4 whit-h is adapted to screw into the socket, said plug being slightly larger in diameter than the lamp at the point where the lamp oud orders the plug. This forms a lmlililt'i i as lil)\'\li clearly in Fig. 2 ot the drawing.

The l()('l( and seal oon-ists of a split amuilar band i' which is adapted lo onrir lo the end of the lamp sot-lam. the two ends of sal 'l band projecting outwardly to form the arms 7. This band is made ol lou e h, readily bendable. n nu'osiliont material. prol'rrabl i' metal. This lot-king band, as shown in the drawing is formed with an annular slot 8 substantially midway between the longitudinal edges thereof, and ext nding awross illlrslot are transver e outwardly rurwd bridge pieces 9. The bond i) lil within the slot 8 when the lUt'lC is in position and tho bridge pieces 9 urve outwardly around said brad, as shown rlmnlv in 1h drawinzw It is manifest that the bridge plot-rs may in: as liroid as desired and that the l t may do lll llii. iutlei' '21 the lockingband will be tornn-d with a. groove in its inner sin-law to rrwi't'o th n brad 3 ol the lamp sorkol. 'lhu lovliinij band is provided along a no of its lnllfflUhii ll2Il9(lf 1't with an in'wardiy t\'i'vll li e in; llangrr l() whit-h is :adopinl to Ii! mid r the ll(lll(l('l' .3 formed l. the lamp iilltif when the locking band i iwnl around :i iamp sot-kc! containing a lamp bulb.

looking and sealing device removed from ends 7 of said strip an bunt inn-Mill to the main body of the loekin band, as shown clearly in Figs. 1 and 3 0 the drawing.

It is manifest that by placing the locking band around the lamp socket with the look ing flange 10 under the shoulder 5, the bead 3 projecting into the slot 8 and then riveting together the two ends 7 of the locking band, the lamp bulb is securely locked in position and it will be impossible to detach said lamp from said socket without first removing the locking band. It is also manifest that the lamp may be turned slightly in the lamp socket after the clamping ring is in position thereon. This is important for the reason that if the lamp is rigidly locked againstall movement it is likely to be broken by persons endeavoring to detach it. If, however, the lamp turns readily for a limited distance and then becomes rigidly locked they are warned that the lamp is not secured in p0 sition in the ordinary manner and no attempt will be made to force the screw plug outwardly through the clamping and seal ing device.

We preferably form the tubular rivets of soft metal so that they may be readily removed with a proper tool. They will curely hold the two ends of the locking band together under ordinary conditions and will prevent the detachmentot the locking band, unless some special tool is employed to re move the fastening rivets.

It will, of course, be understood that any suitable form of fastening device may be employed and we do not wish to be limited in this respect. other changes and modifications may be made in the structure within the scope of the invention.

It will, of course, be understood that the removable tubular rivets merely exemplify one form of removable fastening means which may be employed in this device. Any suitable form of rei'novable or breakable fastening devices may be employed. and we, of course do not wish to be limited in this respect.
